Global estimates of gravity wave momentum flux from High Resolution Dynamics Limb Sounder observations
M. J. Alexander,John C. Gille,John C. Gille,C. Cavanaugh,M. T. Coffey,C. Craig,T. Eden,Gene Francis,C. Halvorson,James W. Hannigan,R. Khosravi,Douglas E. Kinnison,Hanna Lee,Steven T. Massie,B. Nardi,John J. Barnett,Christopher L. Hepplewhite,Alyn Lambert,V. Dean +18 more
TL;DR: In this article, a wavelet analysis technique was proposed to determine covarying wave temperature amplitude in adjacent temperature profile pairs, the wave vertical wavelength as a function of height, and the horizontal wave number along the line joining each profile pair.
Journal ArticleDOI
Tropospheric intrusions associated with the secondary tropopause
Laura L. Pan,William J. Randel,John C. Gille,William D. Hall,B. Nardi,Steven T. Massie,Valery Yudin,R. Khosravi,Paul Konopka,David W. Tarasick +9 more
TL;DR: In this paper, the authors investigated deep intrusions of tropospheric air into the lower stratosphere above the subtropical jet, characterized by low ozone concentration and low static stability.
Journal ArticleDOI

TL;DR: In this paper, a comprehensive quality assessment of the ozone products from 18 limb-viewing satellite instruments is provided by means of a detailed intercomparison, focusing on mean biases of annual zonal mean fields, interannual variability, and seasonal cycles.
